RAILWAY CROSSING AND ALARM SIGNAL.

Application filed January 30, 1923. Serial No. 615,793.

To all whom it may concern:

Be it known that 1, WILLIAM 'W. PHIL- LIPS, a citizen of the Dominion ofCanada, and resident of Calgary, in the county of Cal ary and Provinceof Alberta, Dominion of lanada, have invented certain new and usefulImprovements in Railway Crossing and Alarm Signals, of which thefollowing is a specification.v

This invention has relation to certain new and useful improvements inrailway signals and has for its primary object the provision of signalsof the character stated especially adapted for use at railway crossingsto give audible signals or alarms as the trains and other rolling stockapproach the crossing.

Another object of the invention resides in the provision of railwaysignals of the character set forth which'will be extremely simple inconstruction and operation, inexpensive, composed of the minimum numberof parts and accurate andeificient in its operation.

The invention has fora further object the provision of a railway signalof the character stated which may be readily installed at any pointdesired along the track without alterations in the track constructionand which will be arranged in such a manner as to be positively operatedby the rolling stock as it passes along the track.

\Vith the foregoing and other objects in view as will appear as thedescription proceeds, the invention consists in the novel construction,combination and arrangement of co-operating elements as hereinafter morespecifically set forth, claimed and shown in the accompanying drawingsforming a part of the present application, in which:

Fig. 1 is a plan view of a section of a track, showing the railwaysignal in position.

Fig. 2 is an elevation of the signal showing the track in longitudinalsection for the sake of clearness.

Fig. 3 is an enlarged detail section substantially on the plane of line33 of Fig. 2, looking in the direction indicated by the arrows.

Fig. 4 is an enlarged detail fragmentary elevation, showing the bell andthe striking means therefor forming a part' of the invention.

Fig. 5 is an enlarged fragmentary detail section, showing one of theenclosed guide pulleys for the cable.

Fig. 6 is" an enlarged fragmentary detail of the wheel actuated trippositioned at the side of one of the track rails.

Fig. 7 is an enlarged fragmentary section substantially on the plane ofline 77 of Fig. 2, looking in the direction indicated by the arrows.

Referring more in detail to the drawings in which similarreferencecharacters designate corresponding parts throughout the severalviews, 10 designates in general a track section including the rails 11supported in the usual manner on the transverse ties 12. A signal post13 is mounted outwardly of or to one side of the track, as shown clearlyin Fig. l and preferably located near a railway crossing to carry theusual crossing sign 14. The audible signal 15, preferably in the form ofa gong or hell, is also mounted on the signal post 13 and operated bythe strikin hammer 16, as shown clearly in F ig. 4. T e striking hammer16 is pivotally mounted on the signal post 13, as shown at 17. Thestriking hammer 16 is mounted so that the head 18 thereof may readilystrike upon the gong or bell and the operating cable 19 is connectedwith the other end of the striking hammer 16 which extends into theupstanding section 20 of the cable enclosing tubing, a suitable slot 21being provided in said upstanding section 20 for this purpose, as shownclearly in Fig.

4. The upper end of the upstanding section 20 is closed by a cap 22 orother suitable means. A spring 23 is employed for retaining the strikinghammer 16 in normal position, one end of the spring 23. being mounted onthe signal post 13 while the other end is pivotally connected with thestriking hammer 16at a point near its pivot connection 17 and'theendconnecting with the operating cable 19, thereby resiliently retainingthe head 18 of the strikin hammer 16 adjacent the gong or bell. uitablesupporting straps or brackets 24. are employed to secure'the upstandingsection 20 to the signal post 13, as "shown in Figs. '2 and 4. j r Oneend of the transverse section 25of the cable enclosing and protectingtubing is connected with the lower end of the-upstanding section 20 bymeans of an L or verse section is" extended beneath a Suitablesupporting straps or brackets 29 areemployed for holding thelongitudinal section 23in proper position, as shown in Figs 1 and2; Itmayalsobe stated at this time that the free: end of the longitudinal 1section 2.8 is open and one end of the operatingcable 19 projects out ofthe same. Attention; is also directed, at this time, to the fact thatthe operating cable 19 passes around suitable. guide pulleys 30 whichare located in the L or corner connections 26 and 27' and carried onsuitable pivot pins 31,, as. shown iniEig, 5.

I The end of. the operating cable 19 pro jectiiig from. the open end ofthe longitudinal section 28-. of the cable enclosing and-protecting.casing is connected with the upstanding arm 32 of the wheel actuatedrock arm; 33; This wheel actuated rock arm. 33 is mounted onthe pivotbolt 34:

; inthe:- connection of its main portion with the upstanding arm 32thereof. This pivot belt. 34:iS car-riedon the upstanding branch 35 of:the supporting plate 36. This supporting plate 36 is; mounted on thetransverse ties.- 12, as shown inFig. 1, so as to position theupstanding branch 35 thereof against. the'inner side of the web'of oneof the nails 11; This permits mounting of the wheel actuated rock arm 33adjacent the innerv side of the rail 11, as shown clearly in thedrawings: The upstanding arm 32 is; located at one end of'the wheelactuated rock arm 3.3:and an arcuate head 37 is car ried on. the otherupstanding end 38 of the wheel actuated rock arm 33, as shown clearly'inFig, 6;. A leaf spring 39 or other suitable member is carried on theunder face oflthe'. wheel actuated rock arm 33 to resiliently retain thelatter in its uppermost position, thereby presenting the arcuate head 37inthe path of travel of wheels of the rolling. stock moving over therail 11 adj acent which thewheel. actuated rock arm 33 lSi mounted. A.stop pin. 40 is extended laterally from the upstanding branch 35 of thesupportingplate 36 to limit upward swinging movement of the wheel.actuated rockiarm133,asa disclosed in Fig.6 as well as Figs. 2 and 3. Asindicated by dotted lines in Fig. 6, I the wheel actuated rock arm. 33-will be. forced. downwardly as a Wheel; moving 'ontheirai'l, 11 over thearcuate head As; soon as. the wheel passes: the arcuate head 37,however, the leaf spring as'the rolling stock moves along the track pastthe wheel actuated arm 33.

It is believed the complete construction and operation of the railwaysignal may now be apparent from the foregoing paragraphs taken inconnection with the accompanying drawings without further detaileddescription. It may be briefly stated, however, that the guide pulleys30 provide for a free movement of the operating cable 19 and aspractically all of the operating cable is enclosed and protected and theother operative parts of the signal are so positioned as to be wellprotected from snow, ice and the like the complete signal should operatejust as effectively in bad'or snowy weather as in good weather. In fact,additional covering and protecting members may be employed for theoperative parts, as desired.

While the preferred embodiment of the invention has been disclosed, itis to be understood that minor changes in the details of construction,combination and arrangement of co-operating elements may be resorted towithin the scope of what is claimed without departing from the spirit ofthe invention.
